Quantum Cascade Lasers N2O Sensor

Gasboard-2522
Gasboard-2522 is a high-precision N2O gas sensor based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) and employing a quantum cascade laser (QCL) source. It is designed for highly selective and sensitive N2O measurement in automotive exhaust emission monitoring under the latest Euro 7 performance requirements. Gasboard-2522 integrates a high-quality optical probe with a proprietary gas cell to deliver high measurement accuracy, high sensitivity, strong resistance to cross-gas interference, and long-term stable operation. Featuring a modular design, Gasboard-2522 supports easy installation and system integration. Calibration and configuration are available via an RS485 communication interface.
Applications include automotive exhaust emission monitoring, environmental monitoring, and laboratory research.
Segment: Automobile Exhaust Gas Analyzer
Division: OEM Gas Bench
